This study is a Phase 2b study designed to evaluate the efficacy, safety, and tolerability of PRO 140 monotherapy for the maintenance of viral suppression in subjects who are stable on combination antiretroviral therapy.
Consenting subjects will be shifted from their combination antiretroviral regimen to PRO 140 monotherapy for 12 weeks. Total treatment duration with PRO 140 will be 14 weeks with the one week overlap of existing retroviral regimen and PRO 140 at the beginning of the study treatment, and one week overlap at the end of the treatment in subjects who do not experience virologic failure.

Drug: PRO 140 350mg weekly SQ injection.
- Time to Virologic Failure after initiating PRO 140 monotherapy. Virologic failure is defined as two consecutive HIV-1 RNA levels of ≥ 400 copies/ml separated by at least 3 days. [ Time Frame: 14 Weeks ]
- Proportion of Participants with Virologic Failure after initiating PRO 140 monotherapy at or prior to Week 14. [ Time Frame: 14 Weeks ]
- Mean change in Viral Load (HIV-1 RNA levels), at each visit within the 14-week treatment phase [ Time Frame: 14 Weeks ]
- Mean change in Viral Load (HIV-1 RNA levels), within the 14-week treatment phase [ Time Frame: 14 Weeks ]
- Mean change in CD4 cell count, at each visit within the 14-week treatment phase [ Time Frame: 14 Weeks ]
- Mean change in CD4 cell count, within the 14-week treatment phase [ Time Frame: 14 Weeks ]
- Tolerability of repeated subcutaneous administration of PRO 140 as assessed by study participants (using Visual Analogue Scale) and by investigator-evaluation of injection site reactions. [ Time Frame: 14 Weeks ]
- Frequency of Grade 3 or 4 adverse events as defined by the DAIDS Adverse Event scale [ Time Frame: 14 Weeks ]
- Frequency of Treatment-emergent serious adverse events [ Time Frame: 14 Weeks ]
